As Miakoda said, they aren't doing it for recreation, intercourse for recreation or love is only between women in that society. They do it as more of a chore in order to reproduce, as men are basically just for making babies.

okaaay...i was confused by the word "recreation"
i assumed this was synonym for "re Production" (re Creation) (the word was actually procreation,so i mistaken it for recreation )
much confusing word wow

Ahh okay, I can totally see how that misunderstanding could be made if you saw it as Re-Creation instead. Well just for future reference, Recreational activities are often done for enjoyment, amusement, or pleasure and are considered to be "fun".

No worries, I'm sure we've all had this happen at one point in our lives
